Background: Aortic arch anomalies are rarely encountered among the causes of dysphagia. Kommerell’s
diverticulum is a rare formation originating from persistent dorsal aortic roots. It generally gives
rise to an aberrant subclavian artery and is commonly associated with right aortic arch.
Case report: In this paper we present a 28 year-old man with right aortic arch with an aberrant left subclavian artery originating from Kommerell’s diverticulum which results in dysphagia.
Conclusions: In cases of aberrant subclavian arteries passing posterior to the esophagus the ring may cause
symptoms related to compression of trachea or esophagus. Also, Kommerell’s diverticulum itself
may cause an additional compression on esophagus. Therefore, Kommerell’s diverticulum should
be kept in mind in the differential diagnosis of dysphagia
